Disgraced reality TV star Jason Wahler feels extremely “ashamed” after he was arrested again last week for allegedly driving under the influence.

The former “The Hills” star was taken into custody in Newport Beach last Friday, just days after finding himself in trouble with police in Mexico following a bar brawl.

It was his latest alcohol-related arrest in recent years – he was busted in Seattle last year and charged with assault and minor drinking following a scuffle, while he was ordered to attend rehab in 2008 after punching a tow truck driver in the face. He was also jailed in 2007 for fighting in the lobby of a Seattle hotel.

Wahler is disappointed by his own bad behavior and has apologized to fans of the popular MTV series.

He tells Usmagazine.com, “I am very, very ashamed of everything. I am very sorry for everything that’s happened.”

Wahler claims he “lost contact” with his Alcoholics Anonymous (AA) sponsor after getting “distracted,” adding, “(I) started falling out of the program… It was one drink or a few. It wasn’t a binge or anything.”

He resumed his sobriety meetings on Wednesday, March 24 and Wahler is determined to kick his addiction – before it kills him.

He says, “I never want to drink again. If I don’t stay sober. I am not going to have a life.”
